This document includes the
programming specifications for the
following devices:
1.0 OVERVIEW
The PIC16F72X and PIC16LF72X devices are
programmed using In-Circuit Serial Programming™
(ICSP™). This programming specification applies to
the PIC16F72X and PIC16LF72X devices in all
packages.
The PIC16F72X devices operate from 1.8 to 5.5 volts
and the PIC16LF72X devices operate from 1.8 to 3.6
volts. All other aspects of the PIC16F72X with regards
to the PIC16LF72X devices are identical.
1.1 Hardware Requirements
PIC16F72X and PIC16LF72X devices require one
power supply for V
DD and one for VPP. (See
Section 8.0 “Electrical Specifications” for more
details.)
1.2 Pin Utilization
Five pins are needed for ICSP™ programming. The
pins are listed in Table 1-1.

Legend: I = Input, O = Output, P = Power
Note 1: To activate the Program/Verify mode, high voltage needs to be applied to MCLR/VPP input. Since the
MCLR
/VPP is used to provide high voltage during programming, the programmer must be able to supply
current on this pin.
